PolyMax is a family of advanced 3D printing filaments produced with Polymaker’s Nano-reinforcement technology, to deliver exceptional mechanical properties and printing quality. PolyMax PC is an engineered PC filament combining excellent strength, toughness, heat resistance and printing quality. It is the ideal choice for a wide range of engineering applications. Technology PolyMax™ PC features Polymaker's Nano-reinforcement technology: Nano-reinforcement technology is applied to produce filaments with excellent mechanical properties and printing quality. It dramatically improves the toughness of the material by increasing its impact resistance. Nozzle Temperature: 250˚C – 270˚C Printing Speed: 30mm/s – 50mm/s Bed Temperature: 90˚C – 105˚C Bed Surface: MAGIGOO PC BUILDTAK Cooling Fan: OFF Other: When printing with PolyMax™ PC it is recommended to use an enclosure. For large part it is recommended to use a heated chamber. It is recommended to anneal the printed part right after the printing process to release the residual internal stress. Annealing settings: 100˚C for 2h
